[0 all whont it natty concern.-

Be it known that I, ELBERT O. HAsKINs, a citizen of the United States,residing at Rutherford, in the county of Bergen and State of New Jersey,have invented an Improvement in Hinge and Catch Plates for Boilers andFurnaces, of which the following is a specification.

Heretofore the tions of steam and air fL cast-metal bodies orsechot-water boilers and hotwith integral plane of the they were veryliable to be broken off in trans portation. WVhere these parts werebroken surface; remove the possibility of such inconvenience. Incarrying out my invention the cast frame or section of the boiler orfurnace at the opening'to receive a door is thickened at predeterminedplaces, which are provided with dovetail slots from the edges inward,forming recesses in the surface of the metal open to the edges of thedooraperture.

'nge or catch plates agree in dimensions with the longitudinal andcross-sectional configurations of such slots, and they are adapted to bereceived therein and driven or forced to place. Each of these platescarries a lug formed therewith, either with a hole for the 'nge pin oras a catch for the latch or nosing of the door.

In the drawings, Figure l is an elevation of a section at one end of asteam or hot-water boiler for the purpose of illustrating theapplication of my invention. Fig. 2 is a perspective view at theleft-hand side of a dooropening, showing a perspective view of thehinge-plates. Fig. 3 is a perspective view at the right-hand side of adoor-opening. Fig. 4'is a perspective view of the catch-plate. Fig. 5 isa sectional plan longitudinally of a hingeplate, while Fig. 6 is anelevation of a hinge-plate alone.

a represents a part of or the whole of one section of a boiler orfurnace provided with door-apertures 5. These door-apertures may be atthe ends of fines which pass through the upper parts of the severalsecapplicable tions going to make up the boiler or furnace, and they mayrepresent the entrance for coal to the combustion-chamber or the openingfor the removal of ashes from the boiler or furnace, it being a factthat my invention is to a steam or hot-water boiler or to a hot-airfurnace wherein a section or shell is made of cast metal.

In forming these parts of cast metal I provide thickened portions a or,in other words, parts at either one or both sides of a dooraperture thatare thickened, both longitudinally and vertically, at a, and these partsare provided with dovetail slots from the edges inward opening in thesurface of the metal, wherein the same form recesses open to the edgesof the door-aperture. This is plainly shown in F g. 3.

provide hinge and catch plates 0 c of a shape to fit the dovetail slots,the outer surface ofsaid plates being narrower than the rear or backsurface and the top and bottom edges diverging or spreading from thewidth of the surface or face to the width of the back. Each of theseplates is formed with a lug, the lug d of the hinge-plate 0 beingprovided with a hole for the hinge-pin of the door and the catch-plate 0provided with a lug (Z in the form of acatch for the latch or nosing ofthe door.

WVhile the hinge and catch plates are respectively in the said dovetailslots, it is the purpose of my invention to ship from the place ofmanufacture to the place of sale and destination the sections or shellof a steam or hot-water boiler or hot-air furnace with said hinge andcatch plates separate, and after the furnace or boiler is set up then toplace the hinge or catch plates in position for use. In this way risk ofbreakage is reduced to a minimum, and as the parts are interchange ablethere is no necessity of fitting these plates to place in the factory.After the boiler or furnace is set up and the hinge or catch platesplaced in the grooves and drivenhome to position for use the said partsquickly rust together, so that it is substan tially impossible to removethem and they become to all intents and purposes for use an integralstructure.

In one part of the drawings I have shown a upon the outer surfacethereof for the hinge ing With said slots and having lugs formed andcatch of the door.

2. The combination With the cast-metal body or section of a steam orhot-Water boiler or hot-air furnace having thickened Walls atpredetermined places and at said places provided With dovetail slotsfrom the edges inward forming recesses in the surface of the metalopening to the edges of the door-aperture, of hinge and catch platesWhich agree in dimensions With the longitudinal and crosssectionalconfigurations of such slots and adapted to be received therein, andlugs formed upon the outer surface of said hinge and catch platesprovided with holes for the i face of the metal opening to hinge-pin oras a catch for the latch or nosing of the door.

3. The combination With the cast-metal body or section of a steam orhot-Water boiler or hot-air furnace having Walls thickened bothvertically and horizontally on the inner surface and at predeterminedsaid places provided With. dovetail slots from the edges inward formingrecesses in the surthe edges of the door-aperture, of hinge and catchplates which agree in dimensions With the longitudinal andcross-sectional configurations of such slots so that they are Wideracross their rear surface than across their outer surface and adapted tobe received therein, and lugs formed With and upon the outer surface ofsaid hinge and catch plates provided With holes for the hinge-pin or asa catch for the latch or nosing of the door.
